FreeGLUT doesn’t have any prebuild frameworks we can use with the OS X compilers. Fortunately, Mac OS X is a type of Unix and we can use unix commands to get it to build and install freeGLUT on OS X. Unfortunatey, OS X has some quirks we need to deal with.The first issue is that newer versions of OS X don’t have X11. You’ll have to installXQuartz, a quartz based port of X.org. Download the dmg and install it.Download the latest source from thefreeGLUT website.
Extract the archive, open a terminal window, cd to the extracted folder.Configure the installation using this command in the extracted folderenv CPPFLAGS="-I/opt/X11/include" LDFLAGS="-L/opt/X11/lib" ./configureWhen you installed XQuartz, it installs X11 to /opt/X11/lib. This command configures the build and tells it to look in /opt/X11/include for headers and /opt/X11/lib for library files.In freeGLUT 2.8.0 there’s a bug in the source code that causes to break in OS X. In the freeGLUT source directory you extracted go to progs -> demos -> smooth_opengl3 and open up smooth_openg13.c.Between lines 101 and 102 there’s a bunch type definitions that are already in glext.h that cause a conflict.

All you have to do is sandwich it in some ifdef macros to make it stop complaining.

Then in the terminal enter the make command (make sure the terminal is in the directory you extracted)make allNow using root privileges, install the library with the command:sudo make installNow that you’ve installed the development libraries, it’s time to start up your IDE/compiler.

有问题，于是把修改的宏去掉。重新make all。没有报错。make install.
再参考：
Start up XCode and create a command line tool project.以后我会去到很多很繁华或苍凉，
